It can be possible also with flange in place - bend spokes (it could go with 1,5mm or cx rays but with 1,8mm it will be hard)Pulling spokes are heads in - as i know it is not immmportant for performance

I am pretty much settled on using Stans 340 (still open to other suggestions though) for my upcoming build with DT 240 hubs, I had thought of using Sapim Laser spokes (28/32), would this be ok? Or should I be looking for something a touch stiffer?

240 rear hub has a narrow flange spacing leading to a less than stiff wheel. Better use something else for this wheelset. A novatec F482 hub is the same weight nearly and give good bracing angles. BDOP has them in 32H drilling I think.

I already have the 240 hubs sitting at home so I was wanting to put them to some use rather buying something else. Would a heavier duty spoke (say sapim race) help overcome this?

Hi ALAN Carbon+, the Stans A340 Rim is only 22.6mm deep. If you don't mind a little more rim weight then the 23W BHS C472w (Kinlin XC279), with a 28mm rim depth (ERD 583mm), 32H 2xDS/NDS, or 3xDS 2xNDS, should be ok (upto about 90/100 kgs). These are a nice strong rim and higher DS spoke tension can be used.

Although if you are 95+kg (especially >100kgs) then Rim depths of 30mm or greater would be better with the 240 hub.

If you weigh <70kg, and produce low to medium power output, then the 32H A340 rim 2xDS/NDS, or 3xDS 2xNDS, should be ok.

Yes race spokes will help alot ALAN carbon. Stans alpha rim has a weight limit of 90kg KLabs and that should be respected. Infact rider over 85kg should avoid the Alpha 340 and XR200 as they are not the stiffest rims on the market.

Wondering about spoke count for a 95kg rider on 38mm carbon rims in 23mm width -- 24/28 durable enough without being too harsh? What about for a 50mm rim? When would you consider 32 spokes on the rear with those rims?

I'm planning on building a 24h Velocity A23 rear wheel with a BHS SL218 hub. Can anyone give me advice on the lacing pattern? I'm going to use Sapim Lasers all around, I was thinking either 1xDS/2xNDS or 2xDS/2xNDS. Also, would using the offset version of the A23 help/hinder even tension on the rear wheel with either lacing pattern?

teleguy 24/28 would be fine I am sure given the stiffness of such rims. The deeper the rim the fewer spokes you need not more. Still 24/28 is not a bad spoke count for a 38mm or 50mm deep rim.

Hl219 The hub you plan to use has flange spacing that are similar to the Miche hubs I use alot of. The DS flange diamter is larger by 3mm and the NDS flange is alot smaller (8mm smaller), these difference make little difference to bracing angles over the Miche hubs. Therefore I would still build with this hub 2xDS/2xNDS although some would say use 1xDS heads in to improve stiffness. If stiffnes is a concern my prefered solution is use thicker spokes like Race DS or use more spokes. 1x lacing on a rear wheel to me is a fudge (it may work well though) to keep the spoke count and weight down while retaining some lateral stiffness and improving tension balance. If tension balnce is a concern then the off centre rim would be an option if its available in 24H drilling (not sure) and then 2xNDS/2xDS will be fine for tension balance. Personally I would not build a 24 spoke rear wheel with A23 rim for anyone as I do not think the rim is stiff enough except for very light <60kg riders.

Thanks for your input. I only weigh about 62kg and being a woman I don't put so much power down either, so I figured 24h would be sufficient for the rear. If I went 2x both DS and NDS with the offset rim do you think my configuration would work, or should I change spoke count or use Sapim Race instead of Lazers or something?
